Hi, you're about to get smarter in just a few minutes, with Curiosity Daily from Curiosity.com.

0:06.2

I'm Cody Goff. And I'm Ashley Hamer.

0:08.2

Today you learn what environmental cardiology has taught us about how we should live with help from Dr. Aruni Botnagar.

0:15.0

Then you learn about the world's first 3D printed nuclear reactor core and why spaghetti always breaks in three.

0:22.0

Let's satisfy some curiosity. why spaghetti always breaks in three.

0:22.8

Let's satisfy some curiosity.

0:25.2

You might be surprised to learn how quickly and how much

0:29.0

your immediate environment can affect your health. For instance, did you know that the California

0:35.2

wildfires in recent years may have led to as much as a 70% spike in heart attacks?

0:41.3

I mean we all know pollution is bad but that's pretty huge.

0:46.3

So to learn more we got in touch with Dr Arunie Botnagar, professor of medicine and

0:51.0

director of the Christina Lee Brown Enverum Institute at the University of Louisville.

0:56.0

He's a pioneering researcher in the field of environmental cardiology,

1:01.0

and he's here with the scoop on some of the surprising ways our environment can affect our health.

1:05.4

There is sufficient evidence to indicate that acute exposure to air pollution and

1:10.8

trigger heart attacks. So there was steady out of Boston and say there's a spike in air pollution, then six hours later there's a spike in heart attacks and admissions to ER. And then there is a 24 hour peak.

1:22.8

So there is a 6 hour and 24 hour peak

1:25.5

after exposure to a high level of air pollution,

1:28.8

which may be due to arrhythmias

1:32.3

and changes in the electrical activity of the heart.

1:35.0

Wow, a six to 24 hours.

1:38.0

That's, uh, I feel like your research should have some pretty big implications for the way that people live.
